Sony A7r II Noise Comparison And Rolling Shutter Test

a7rii

We’re starting to see more and more sample footage from the much anticipated Sony A7R ii, which is due to start shipping August 5th. U.K. based photographer, Jon Roberts, recently got his hands on one of the cameras and was nice enough to whip up this noise test, which compares the A7R II to it’s predecessor the A7R and, also, a Canon 5D MKiii. Roberts’ notes “that this wasn’t a very scientific test under lab circumstances…more of a rough and ready preview!”; however, it’s still a solid comparison with 100% crops.

The same goes for the rolling shutter test video Roberts has shared with us, which you’ll see farther down in this post along with an unboxing video–but, we’ll get to those in a minute.

First, take a look at the noise test. You can click the image to open a full size version in a new browser windor, or take a look at it over on Flickr. [Read more…]

Why Leaf Shutter Lenses Matter

Have you wondered how something as simple as a lens design might shape your approach to off-camera lighting? And what if that same lens could shape how light is recorded within a camera? Add to that this bonus: this same lens might take what you already have and make it four times more effective?

We are approaching an era where camera sensors and mega-pixels no longer matter and the darling of the off-camera lighting world isn’t what you might guess.

Move Over Schlieren, Scientists Are Upping The Sound Wave Photography Ante

Okay, Schlieren photography is still pretty awesome. I’m actually still quite fascinated with our ability to photograph sound waves. I also love that I can do it myself for less than $10.  But, this project announcement from MIT is pretty wicked, too. Scientists from Microsoft, MIT, and Adobe have developed a way to use similar science to recover the audio from images taken using high speed cameras and even a prosumer level DSLR.

Rolling Shutter: Sony A7s Compare to Other Major Players; Meh…

One of the things that cinematographers care about when selecting a camera for shooting is how significant is the rolling shutter effect.

as7-rolling-sutter-03

Rolling Shutter is a ‘side effect where vertical lines in the real universe appear as diagonal lines ‘on film’. For example it smears buildings when shot out of a moving car or create  a jello effect when the shooting camera is unstable, we explained this in length in this post.

The good guys at Cinema5D took the crown challenger – Sony A7S with its remarkable low light performance and put it to the test against some of the other leading video cameras in the market: Arri Amira, Panasonic GH4, (Canon C300), Canon 5D mark III and Canon 1D C. Sadly it did not do all that well.

Following is a break down and explanation of what is Rolling Shutter why it is being used and what are its quarks. [Read more…]
